Hi Riley: I'm sorry about your grandmother. I had a TIA in May which did not show on the CT and they didn't think it was an TIA and they sent me home. Later in May I had a small stroke (that didn't even show on the MRI); they kept me at the hospital, put me on aspirin and sent to in-house re-hab. Well I had a massive brain stem stroke while there which did show on the MRI and I ended up almost dying...was in intensive care paralyzed and am now doing pretty well, by the grace of God, after 5-1/2 months of rehab, altho' I still walk with a walker and my speech still needs improvement. I strongly suggest taking your grandmother to a GOOD neurologist and consider a blood thinner if she can take one. Re-hab in the way of speech therapy should be prescribed plus physical therapy if needed. As an advocate for her, you can help her from having a bad stroke and get her life back 100% and stop your worrying. But, with me, I guess there was nothing that would have stopped the 2nd stroke so nobody is to blame. I still really like my doctor. I guess I am suppossed to be some type of an example like Kate in her book "Kate's Journey". Good luck and God bless you. Leah
